Hi, if you set the it at the beginning of the table creation and then add value it will show the null values on filter. But if you update/change table setting after the values are entered then the table function neds to be rerun.
I deleted and recreated the column in Rowy and redeployed the function and set the default to null. However, the documents with null value are still not showing, even though I can query them from Node with .where('neighborhood', '==', null)
